LOCK.

Application filed. August 28, 1917.

To all whom it may concern:

Be it known that I, Gnoncn DANIEL WIsnLY, a citizen of the UnitedStates, residing at Blairstown, in the county of Henry and State ofMissouri, have invented a new and useful Lock; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to the art of locks and latches, and particularlyto an improved lock, and an object of the invention is to provide adevice of this kind, which is simple, efficient, and practical inconstruction, and may be manufactured at a small cost and sold at areasonable profit.

A further object of the invention is to provide a gravity actuatedlocking bolt.

A further object of the invention is the provision of means undertension of a spring for holding the gravity actuated means of saidboltactuated.

A further object of the invention is to provide said holding means withimproved means for securing said holding means out of engagement withsaid gravity actuated means.

In practical fields the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts ashereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in side elevation of the improvedlock constructed in accordance with the invention.

Fig. 2 is a sectional view through the easing of the lock, showing thegravity actuated bolt and the key actuated bolt in elevation.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Fig. A is a detail view of the gravity actuated holding means, showingthe rib for holding said holding means out of engagement with thegravity actuating means of said bolt.

Referring more especially to the drawings, 1 designates a lock casingwhich may be of any suitable shape, preferably rectangular, as shown inFigs. 1, 2 and 3, and is provided with laterally extending flanges 2having screw receiving apertures 3, to receive screws A to secure thecasing to the door 5. Projecting from one wall of the Specification ofLetters Patent.

casing is a pair of laterally extending bars 6, which pass through theelongated slot 7 of a locking bolt 8. This bolt 8 is provided with apair of downwardly extending spaced lugs 9. Also projecting from thewall carrying the bar 6 is a pin 10, which is designed to be telescopedby the barrel 11 of a key. This pin 10 protrudes from its wall in such amanner as to assume a position between the lugs 9, so that by turningthe key, the tongue 12 of the key barrel will cooperate between and withthe lugs 9 for throwing the bolt 8 in one direction or the other,whereby. its end 13 may engage or disengage its keeper, (not shown).Guided in the guide straps 1A in the lower part of the casing 1 is abolt 15, the usual beveled end 16 of which is adapted to automaticallyslide into engagement with its keeper (not shown). The upper edge of thebolt 15 is provided with a series of rack teeth 17. A shaft 18rectangular in cross section extends transversely of the casing 1. Thisshaft where it passes through the door 5 has a cylindrical part 19.Secured by screws 20 on both ends of the shaft are the sleeves 21 of theusual door knobs 22, whereby said shaft may be rocked by either knob. Asegment member 23 having teeth 24 to mesh with the teeth 17 is provided.The segment member 23 has a rectangular openinv 25 through which therectangular part of the shaft 18 extends. Formed integral with thesegment member where it is connected to the shaft is a segment shapedweight 26, the gravitation of which actuates the segment 23, whereby thebeveled end 16 of the bolt 15 is thrown into engagement with its keeper(not shown). When rocking the shaft by turning either knob in thedirection of the arrows a, and b of Figs. 2 and 3 respectively, theweight 26 is raised, and the bolt 15 is moved out of engagement with itskeeper. The casing 1 has an integral cylindrical tubular auxiliarycasing 27 having a flanged cover 28 threaded thereto. A pin 29 ismounted in guides 30 and 31 of the wall of the casing 1 and the cover28. A disk 32 is carried by the pin 29, and interposed between the diskand the cover and surrounding the pin is a spring 33, to hold the innerend of the pin 29 normally in the path of the weight 26, to prevent theweight from being raised, and consequently holding the bolt 15 locked.In this way the pin 29 constitutes a night latch for the bolt 15. The

pin 29 is provided with a rib 34:, which, when the pin is normally inthe position as shown in F ig.2, engages a recess 35 in the wall of theguide 31. It is to be noted, that by grasping the head 36 of said pin,pulling outwardly on the pin, and partially rotating or rocking thesame, the inner end of said rib may engage on the outer face of thecover 28 out of alinement with the recess 85, thereby holding the innerend of the pin 29 out of the path of the weight 26, as illustrated inFig. 1 clearly, therefore, in this case the bolt 15 may be freelyactuated by the shaft 18 and the weight 26. When the segment weight 26gravitates the casing a 37 will limit the segment weight in itsgravitating movement. It is to be noted that segment weight 26 may beraised and the pin 29 thrown in its path, thereby holding the bolt 15retracted.

The invention having been set forth what is claimed as new and useful isIn a lock, a casing, a bolt having a beveled end portion penetratingthrough one of the edge walls of the casing, a pair of arched strapguides mounted on the interior of the casing and in which said bolt isguided, said bolt having rack teeth, a knob actuated shaft extendingtransversely of the casing Copies of this patent may be obtained for anlhaving a rectangular portion, a segment fitting said rectangular portionand having teeth meshing with the teeth of the rack of said bolt, asegment weight integrally carried by the first segment, whereby theleveled end portion of the bolt is held protruded beyond the edge wallof the casing, and means to be thrown in the path of the segment weightto hold the same in its gravitated position, and the bolt extended,

means to limit said segmentweight in its gravitated position, said firstnamed means comprising a spring 'tensioned'pin, a holder casingtherefor, said pin having means, whereby, when the pin is withdrawn andpartially rotated, said pin will be held out of the path of the segmentweight, said pin when actuated by a spring and the segment weightraised, said pin will lie in the path of the segment weight andhold thebolt retracted.

In testimony whereof I have signed my name to this specification in thepresence of two subscribingwitnesses;
